confirming that 4.9.2 compiled on RHEL6 does not crash on same source.

You haven't attached the /tmp/ccYM4plV.out the compiler told you to attach (or whatever other file when you rerun it).  Without that there is nothing we could do.

Can't reproduce, works just fine with gcc-c++-4.4.7-11.el6.x86_64.rpm here.

doing a fresh install, will make more detailed steps to reproduce.

Even that works for me fine.

I am sorry, but I did not believe you last time, so I left out a step as a test.

wxGTK-devel is not on RHEL6, you could not have completed that command on a fresh install.

Would you like the VM image of the test system?

I run what you've provided:
/usr/libexec/gcc/x86_64-redhat-linux/4.4.7/cc1plus -quiet -mtune=generic -O2 -Wall -Wno-unused-parameter -fno-strict-aliasing -fdata-sections -ffunction-sections cc5F214H.out
And that doesn't reproduce it.

That is not the comamnd I provided. I do not know where you got that command.

Below is the command in context, as in the attached file.

[root@one-hundred-twenty-two-123 Main]# pwd
/root/CipherShed/src/Main
[root@one-hundred-twenty-two-123 Main]# /usr/libexec/gcc/x86_64-redhat-linux/4.4.7/cc1plus -quiet -I/root/CipherShed/src -I/root/CipherShed/src/Crypto -I/root/CipherShed/src/Main -I/usr/lib64/wx/include/gtk2-unicode-release-2.8 -I/usr/include/wx-2.8 -MMD Unix/Main.d -MQ Unix/Main.o -D_GNU_SOURCE -D_REENTRANT -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGE_FILES -D TC_ARCH_X64 -DTC_UNIX -DTC_LINUX -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__ Unix/Main.cpp -quiet -dumpbase Main.cpp -mtune=generic -auxbase-strip Unix/Main.o -O2 -Wall -Wno-unused-parameter -fno-strict-aliasing -fdata-sections -ffunction-sections -o - -frandom-seed=0

That is the same command, with the useless options filtered out.  The file is already preprocessed, so there is no point for -I, -D options, -M* is also undesirable, -dumpbase/-auxbase-strip too, -o - too.
Do you say that you can reproduce it with the #c12 command and not with #c11 command?

Affirmative.

/usr/libexec/gcc/x86_64-redhat-linux/4.4.7/cc1plus -quiet -mtune=generic -O2 -Wall -Wno-unused-parameter -fno-strict-aliasing -fdata-sections -ffunction-sections cc5F214H.out 

does not error.

The problem appears to be in the preprocessor step:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64414#c1

For lazy sake:

I added this yum repo for the 2nd test instead of rebuilding from tarball to get wx.

rpm --import http://mirrors.kernel.org/centos/6/os/x86_64/RPM-GPG-KEY-CentOS-6
cat > /etc/yum.repos.d/extras.repo<<EOF
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirror.centos.org/centos/6/extras/$basearch/
gpgcheck=1
EOF

Then obviously the preprocessed source is not useful.
Does it crash if you replace remove the -M* options from the command line (or just some of them)?  Does it ICE if you replace -c with -E ?  Can you remove some command line options and have it still crash?  Can you remove some headers and have it still crash?  For preprocessor ICE it is best to just create a minimal self-contained testcase and package the tree with all the necessary sources and headers needed to reproduce it.

We find ourselves calling get_fileinfo with NULL.  Trying to reduce it somehow...

This happend when I added in the src/Main/Unix/System.h which was an include for ../System.h but beyond that I was unable to trouble shoot it.

My workaround was to include ../System.h in each file explicitly.

I think the following should reproduce the issue:

$ mkdir -p t/a; cd t
$ cat > x.h <<< '#include "xx.h"'
$ cat > a/x.h <<< '#include "../x.h"'
$ cat > a/m.C <<< '#include "x.h"'
$ touch xx.h
$ g++ xx.h -O -D_GNU_SOURCE -D_REENTRANT -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGE_FILES -D TC_ARCH_X64 -DTC_UNIX -DTC_LINUX  -D__WXGTK__ 
$ g++ -c -D_GNU_SOURCE -D_REENTRANT -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGE_FILES -D TC_ARCH_X64 -DTC_UNIX -DTC_LINUX  -D__WXGTK__ -O a/m.C

less cruft, and a self validation.

$ mkdir -p t/a; cd t
$ cat > x.h <<< '#include "xx.h"'
$ cat > a/x.h <<< '#include "../x.h"'
$ cat > a/m.C <<< '#include "x.h"'
$ cat >> a/m.C <<< 'int main(int argc, char** argv){return 0;}'
$ g++ a/m.C
$ ./a.out
$ rm -f a.out
$ g++ xx.h
$ g++ -c a/m.C

# LD_LIBRARY_PATH=/root/mpc/lib/:/root/bin/gcc-4.9.2/lib/../lib64 \

more random stuff:

$ rm -f xx.h.gch m.o a.out
$ cp xx.h.gch.4.9.2 xx.h.gch
$ g++ -c a/m.C

does not crash

$ rm -f xx.h.gch m.o a.out
$ cp xx.h.gch.4.4.7-11 xx.h.gch
$ LD_LIBRARY_PATH=/root/mpc/lib/:/root/bin/gcc-4.9.2/lib/../lib64 \
/root/bin/gcc-4.9.2/bin/g++ -c a/m.C

does not crash

$ rm -f xx.h.gch m.o a.out
$ cp xx.h.gch.4.4.7-11 xx.h.gch
$ g++ -c a/m.C

crashes.

The fix looks very safe.

LGTM, but then we shouldn't backport just r151970, but also r185029.

Fixed.

QE: We don't have an internal test case for this, so you can use what's in Comment 22 and Comment 23.
